redhat-config-services currently has an "Exit" button in the toolbar. The GNOME
Human Interface Guidelines (http://developer.gnome.org/projects/gup/hig/) advise
against such a practice:
"Don't add buttons for Help, Close or Quit to your toolbar by default, as these
are rarely used and the space is better used for more useful controls.
Similarly, only provide buttons for Undo, Redo and the standard clipboard
functions if there is space on the toolbar to do so without sacrificing more
useful, application-specific controls."
Also, no other Red Hat tools provide an Exit button on the toolbar, so I suggest
for it to be removed from redhat-config-service if just for the sake of consistency.
